These are some very easy pro active measures that I pulled of the CDC web site, they are very easy to follow and will help in keeping you healthy
All travelers should take the following precautions, no matter the destination:
Wash hands often with soap and water.
Because motor vehicle crashes are a leading cause of injury among travelers, walk and drive defensively. Avoid travel at night if possible and always use seat belts.
Always use latex condoms to reduce the risk of HIV and other sexually transmitted diseases.
Don’t eat or drink dairy products unless you know they have been pasteurized.
Don’t share needles with anyone.
Eat only thoroughly cooked food or fruits and vegetables you have peeled yourself. Remember: boil it, cook it, peel it, or forget it.
Never eat undercooked ground beef and poultry, raw eggs, and unpasteurized dairy products. Raw shellfish is particularly dangerous to persons who have liver disease or compromised immune systems.
Travelers visiting undeveloped areas should take the following precautions:
To stay healthy, do...
Drink only bottled or boiled water, or carbonated (bubbly) drinks in cans or bottles. Avoid tap water, fountain drinks, and ice cubes. If this is not possible, make water safer by BOTH filtering through an “absolute 1-micron or less” filter AND adding iodine tablets to the filtered water. “Absolute 1-micron filters” are found in camping/outdoor supply stores.
If you visit an area where there is risk for malaria, take your malaria prevention medication before, during, and after travel, as directed. (See your doctor for a prescription.)
Protect yourself from mosquito bites:
Pay special attention to mosquito protection between dusk and dawn. This is when the type of mosquito whose bite transmits malaria is active.
Wear long-sleeved shirts, long pants, and hats.
Use insect repellents that contain DEET (diethylmethyltoluamide).
Read and follow the directions and precautions on the product label.
Apply insect repellent to exposed skin.
Do not put repellent on wounds or broken skin.
Do not breathe in, swallow, or get into the eyes (DEET is toxic if swallowed). If using a spray product, apply DEET to your face by spraying your hands and rubbing the product carefully over the face, avoiding eyes and mouth.
Unless you are staying in air-conditioned or well-screened housing, purchase a bed net impregnated with the insecticide permethrin or deltamethrin. Or, spray the bed net with one of these insecticides if you are unable to find a pretreated bed net.
DEET may be used on adults, children, and infants older than 2 months of age. Protect infants by using a carrier draped with mosquito netting with an elastic edge for a tight fit.
Children under 10 years old should not apply insect repellent themselves. Do not apply to young children’s hands or around eyes and mouth.
For details on how to protect yourself from insects and how to use repellents, see Protection against Mosquitoes and Other Arthropods.
To prevent fungal and parasitic infections, keep feet clean and dry, and do not go barefoot.
